Descrição: dc.descriptionSalmonella spp. are intracellular, Gram-negative pathogens responsible for a range of diarrheal diseases, which can present either as self-limited (gastroenteritis) or as a systemic form (typhoid fever), characterizing a serious public health problem. In this study, we investigated the therapeutic effects of oral administration of Saccharomyces cerevisiae CNCM I-3856 in a murine model infected with Salmonella Typhimurium (ST). This yeast species has previously demonstrated the potential to support immune function and reduce inflammation and the ability to exert antimicrobial activity, which is important considering the increasing prevalence of antibiotic-resistant bacteria. Our findings revealed that mice infected with ST and only treated with sterile saline exhibited a higher mortality rate and body weight loss. In contrast, mice treated with I-3856 showed a notable reduction in these adverse outcomes. The yeast demonstrated a high capacity for co-aggregation with the pathogen. Furthermore, the significant amounts of yeast found in the feces of treated mice suggest that intestinal colonization was effective, which was associated with several beneficial effects, including reduced intestinal permeability, which likely limits bacterial translocation to extraintestinal organs. Additionally, the administration of I-3856 reduced levels of sIgA and resulted in a decrease in the recruitment of neutrophils and eosinophils to infection sites, indicating a modulation of the inflammatory response. Histological analyses showed attenuated liver and intestinal lesions in the yeast-treated mice, corroborating the protective effects of the yeast. In conclusion, the results suggest that S. cerevisiae CNCM I-3856 has the potential to control the inflammatory response experimentally induced by S. Typhimurium when administered to mice.-
